If the content is too complex to eloquently condense information into 140 characters or fewer, the best thing to do is tweet out only the most relevant information with a link that includes all the details. "11:33PM train from Huntington to Penn Station will arrive 14 minutes late at 12:54AM. Details at mta.info/0123456789abcdefghijklm." Their content management system could even be set up to have a box for the content writer to put in the Twitter-friendly version of and automatically send the Tweet including the link back to the full details.
The $9M price tag seems steep, even considering that they have a YouTube channel with decent production quality. Do they do it in house?
